I have a G-27 with very few rounds through it; 200 to 500 rounds over the 6 years I've owned it. It's my carry gun but I carry with premium ammo. S/N FSE2XX. I remember on previous range trips that it would jam from time to time. Each time it was using UMC 180 grain (I think) ammo. I decided to try it out again yesterday and as suspected, I had a jam once in 75 rounds. I tried some Federal Hydra-shock and some Speer Lawman and had no problems. I probably shot about 120 rounds through it yesterday.

I was also reminded why I don't shoot it very often. It's just painful to shoot, especially with that stupid grooved trigger. I may swap it out for a smooth trigger if I can find one. I used stock G-27 mags, 2 G-22 and 2 G-23 mags.

I'd really like to shoot it more to diagnose the problem but the thought of buying 500 or 1000 rounds of premium ammo makes my wallet quiver.

My friend and I were thinking that it may be that the UMC stuff is just too light to make it cycle properly since it has that compound recoil spring.

Is this a common issue with G-27's?

Thinking of trading it for a Beretta Nano.

My G27 does not like Blazer ammo regardelss of the bullet grain; however my buddies G27 gobbles them up...can't figure out why....my 27 is just partial to other ammo brands; according to Marshall and Sanow the best man stopper for the 40 cal is the 135g jhp from Corbon followed by the 165g Remington Golden Saber followed by the Federal 155g Hydra Shock; my G22 and 27 love all these rounds and they are my CCW ammo of choice depending on what I can find at my local shop....maybe your G27 will like them better than the 180's?

do u think after so many rounds u might be getting a lil recoil sensitive and grip is causing the weapon not to cycle??? i only say this, because i noticed i was getting "hiccups" with my sub compacts and that was the cause.. my normally happens around 150 rounds or so... most of the time i didnt even notice i was oing it, then i was in denial. me recoil sensitive, hell no.... truth is i was and it was due to fatigue...

It takes A Real Man to Admit He Was Shooting 'Limp-Wristed' !!!



Seriously, I think you have a valid point...something to think about...FATIQUE can in fact cause Miskates!!!

The last time I went back to Glock Armourers school before retirement... They told us that the problems they'd been seeing with their .40 S&W pistols were with 180 grain bullets and to stay away from them. When you are having your issues with your .40 are using a one handed or two handed grip?

I've owned a couple of G27s, a G19, a G26, several G23s, and about two dozen of the regular sized Glocks. I also have a LOT of experience building dozens of RELIABLE ultra short Colt Govt .45 pistols [ Detonic/chopped Commander sized slides, coned/ramped barrels, etc ] and I know just how temperamental and ammo sensitive any of the micro sized shorty pistols can be. In fact, I shot a micro sized Detonics Combat Master .45 in IPSC competition for a couple of years, made it to IPSC "B" class with this eminently PRACTICAL little pistol, and even shot the Canadian IPSC championships with my Detonics micro pistol [ and beat a few full sized race guns along the way ].

SO,
I REALLY LIKE SMALL, POWERFUL pistols!!!

BUT,
after four operations on my right wrist,
two operations on my left hand,
and the onset of arthritis in both my hands,
it appears the small, powerful pistols don't like me.

So I down sized from .45 ACP to .40 S&W and 9mm,
and I switched from the Colt Govt model type pistols to the easier recoiling polymer framed Glocks.

I wanted very much to like the ultra compact Glock G26 and the G27, but whenever I shot these micro guns, my practice scores went down about 30 - 40 % of what I could do with a G22 or a G35. The G26 and G27, even with the magazine extenders, in my hands, squirm too much FOR ME on repeat shots. A fast multiple shot string finds me readjusting my grip after the third or fourth shot ... which tells me that these guns are just too small for me to handle effectively.

You might not have this problem ...
YPMMV!!!

I just sold all of my G35s and G22s, which were set up to shoot .40 S&W, 9MM, .357 SIG, and .22 LR [with an Advantage Arms conversion kit ]. While I shoot the G35 more accuratelyin practice and at matches than any other Glock, I decided to cut down to just one pistol, and shoot only the pistol I would carry in real life. Right now the ONE PISTOL I own is my G23. And with the much easier to carry and conceal G23, my scores only go down about 10 % from a full sized Glock G22 or G35.

AS for reliability,
None of my .40 S&W ammo was ever TOTALLY reliable in a G27 FOR ME!! But ALL of my .40 S&W ammo WAS TOTALLY RELIABLE, FOR ME, in the G23 and G22 and G35. With the G26 and G27, shooting one handed, shooting off some barricade positions, or some other positions that required a different grip or stance, and especially, doing CQB "speed rocks" or "step backs" firing from waist height one handed, I could almost guarantee a few "limp wrist" short recoil stoppages with every session. The Glock pistols require a FIRM grip, and the ultra compact Glocks also require a locked wrist for total reliablity.


I also shot off a CASE of [ VERY HOT! ] Canadian Issue IVI 9 mm BALL ammo in my G26 and in a couple of different 9mm conversion barrels in the G27s. With the [ VERY HOT!! ] IVI 9mm, most of the reliability issues disappeared. With most 9mm ammo, I could NOT consider the G26 and the G27 as totally reliable. My take on this, is that the triple wound recoil springs in the super short barreled MICRO Glocks, simply are too short, too harsh and too abrupt, for total reliability in all positions, and with all ammo. The slightly longer and smoother acting spring of the G23, and the regular length springs of the G22 and G35 are much more reliable, for me, with BOTH 9 MM conversion barrels, AND with most .40 S&W commercial ammo.

PS: Right now, I am using a full length HARRT mercury filled guide rod designed for the G22/G35 in my G23, with so far zero malfunctions, and noticeably less recoil on fasdt follow up shots.

My advice to you, if you want TOTAL reliability with a wide range of ammo, would be to trade your G27 for a G23, or even a full sized G22, with the longer/smoother recoil system. The small difference in size between a G27 and a G23 is almost negligible when it comes to concealment, but can make a big difference in reliability.

that is one handy looking peice of weaponry!^^^^

from a guy who has owned/owns my share of Glocks (including a 27), ive never had a bit of problems with any of them. i will say that my G30 is EASILY my most accurate Glock and IMO is easier on a shooter(my 15 yr old daughter LOVES it), followed by a 26, and i agree with the suggestion to try a 23. see how that treats you. GOOD LUCK!

It happened after about 2 or 3 mags of good ammo. It was the first mag with UMC and pretty early on in our shooting session.

The bummer is that I'd really like to reload 40 for it to eliminate the ammo possibility and get the round count up, but I don't trust 40 handloads and unsupported chambers of Glocks. I do it for my Sig, but not the Glock. I guess I could always pull some bullets from UMC ammo and replace them with a Hornady XTP. That would be a cheaper alternative. Lots of work though...

I truly think it was ammo related, but I just wanted to get the word out and see if I wasn't alone. Some other guys on other forums have said it's ammo, others say if it is so problematic, it's unreliable. I like the 40 round but it's not cheap to shoot in Glocks. I may just dump it and go with a G26, G19 or G-23.

Ah, decisions...

Always 2-handed.

I follow this technique to the tee...

mercman

A couple of things that need to be stressed with all pistols is to have your grip as high on the backstrap as possible. Also the support hand needs to be indexed as high as possible on the gun. I index my support had thumb on the takedown button on my Glocks. Glocks can be very sensitive to limp wristing and by keeping your hands positioned high you eliminate on possible factor in a weak grip. My G27 gobbles up whatever I feed it if I do my part.

Tonyben...

I re-read your three posts here, and I noticed that each time you only said 'I' ?

Did your friend also shoot your Glock 27 and have the same issues?

My theory of trouble-shooting is to always eliminate only one variable at a time...

If it could be Ammo...Switch Ammo types and manufacturers One At A Time.

If It Could Be Mags...same thing.

Even compare another Glock, side by side....say a 9mm Model 26.

And, obviously, have a friend or friends at the range...try their hand!

Sometimes when that 'friend' picks up your malfunctioning gun with mis-aligned sights and puts all their shots in the bulls-eye...

You gotta Re-Think It !!!

I reload a LOT of .40 and .45. If you do it right, there's no problems with the reliability. Only problems with Glock's is that they destroy brass, especially if it's loaded hot. They get the "Glock Bulge" and I don't even pick up brass anymore if it's been run through a Glock.

With factory ammo, there's NO SUCH THING as ammo that is too light. I chrono'd all of the UMC, Federal, Winchester.... and boy is that stuff HOT!!!!! SERIOUSLY! (let me check my papers, I've got it all logged)

Power factor = Bullet weight x velocity / 1000

If you come out below 165, that is considered "Light" by USPSA standards. Above 165 is "Hot"

My .40 handloads come out at 169 PF. This is like shooting marshmallows out of my XD. It's totally reliable and very accurate. I Chrono'd UMC ammo a while back... 190PF!!! HOT!!! I wouldn't dare shoot that through a compact POLYMER gun! I'm definitely feeling your pain. And I do believe you limp wristing that ammo is a strong possibility, even though you are of a "hefty" build if I remember.


I'd advise to find a friend with a reloading machine and pay him for the components. Have him load you up 1k rounds of practice ammo and keep the hot stuff for the bad guys. Do NOT shoot lead through it. Reliability shouldn't be a problem if your "Almighty Glock" lives up to the standards that are set upon them.

tonyben

My friend ran a few rounds through it and didn't have the jam. He's about 6"3". I have had others shoot it in the past and they had the problem too but they were inexperienced shooters.

I do have a press and I do reload for 9, 40, 45, 357 sig and 500 S&W. I have loaded 40 in the past but that was for my Sigs. I've been hesitant to try it in my Glock. I did do some 9mm and ran it through my G-17 and didn't have any problems. I do see that Redding makes a separate die that fixes the case bulge from Glocks.

I'm thinking of getting this and loading 40's on the light side.

Thanks,

I started collecting brass well before I got all my reloading equipment. I've got a 5 gallon bucket full of cleaned .40 brass and another 3/4 full of nickel.

My prep work has given me the opportunity to just toss the crappy brass. I don't need it. I shoot too much handgun to have to worry about needing a special die for some bad brass.

You could probably just look into another barrel for your gun. No more of that destroyed brass and you can shoot both lead and jacketed without F'ing up your gun.
