Glock 28 spring for short range ammo

[giova22]

Hello

I own a G28 in 380acp that works 100% with full power ammo. My corp use for indoor training a reduced hazard ammunition with 47grs frangible bullet, they work 100% with Beretta 84F but theyr recoil is not enough to run the Glock 28. I bought a spare spring assembly and started cutting half piece each time the bigger/shorter external spring. The pistol reliability improved a little but, cutting more and more, i arrived at a point the spring tension wasn't enough to keep the slide close. Do you have any ideas to make the pistol reliable with my training ammo?

Sorry for my english

I have always thought the Glock 28 (for those of you who don't know, this is a Glock .380 the size of a 19/23/32) was a seriously neat piece, and have always been a bit bummed it doesn't make the import points to be sold in the US. I don't believe you will find very many people on this board who have any firsthand experience with the Glock 28, have fired one, or have ever handled or even seen one.

Really, only two things occur to me. (1) Go to a different ammo type for training. We get a lot of questions on this board that really come down to, "My gun works with everything else but it won't work with X ammo. What should I do?" The answer, of course, is "Stop firing X ammo. Use something with which the gun does work." Obviously your gun needs more powerful ammo to cycle. (2) Go to a lighter firing pin spring. When the Glock cycles, the firing pin inside the gun hits the rearward portion of the trigger bar on the slide's' forward stroke, compressing the firing pin spring slightly in the process. Lessen the amount of energy necessary to compress that spring, you increase the gun's chances of going all the way into battery.

In summary, I would suggest, if at all possible, going back to a factory stock recoil spring, or one of the lighter than factory stock units that can be found from companies like ISMI, rather than your home cutdown option. Also go to a lighter firing pin spring. Finally, choose training ammo that gives you more energy to operate the action. If the ammo is giving you as little energy to operate the gun as your post indicates, I don't believe that you will ever find it giving you a sufficient level of reliability. Go to something that does.

Thanks for the fast answer.

I'm using that ammo because i can have them for free, i'm a shooting instructor for my national police corp, we have a mix of Beretta 92 and large number of Beretta 84. Duty ammo for 380 acp is 72grs FMJ TC that is a special run for our corp. At the end of shooting session i like to use extra ammo in my G28 because i use a G17 for IPSC production and the have similar ergonomic. Most of time we shoot indoor so most of ammunition available i the short range.

I'm going to buy a light striker spring to try.

Thank you again

Agreed, but they're smaller than the 19/23/32....they're the same frame as the 26/27.

Your idea of an aftermarket spring is likely the only way to go....keep the length so it'll still close the slide, but drop the rate and it may work just fine. I've been told they will sell limited numbers of 28s law enforcement agencies (not counted in their normal import numbers), but I'm not sure how that works...be cool to have one just because. That's actually the same reason why store Glocks normally have the trigger with ridges...it counts as points towards competition guns, versus self-defense guns, or some such silly quota. R,

Actually in my experience it's the compact (19/23/32/etc.) and subcompact (26/27/33/etc.) frame Glocks that have the serrated triggers, because they need a "target trigger" to make the import points. The larger Glocks have smooth triggers. Personally I absolutely loathe those serrated triggers, and routinely change them out for the smooth trigger from a larger Glock.

Well sonuvagun, you're right. I just learned something new.

You know, that makes sense. My G22s all have smooth triggers, but I never thought about it. One of my G22s was issued, but I bought both my G23 and G27....they came with serrated triggers (had them swapped out). Our guys told me that they have a deal with Glock so issued G23s come with smooth triggers, but they might get counted differently considering where they're going. I do know I can't stand the serrated triggers either...they sort of pinch my finger, and it doesn't take long for it to get annoying! R,

It occurs to me that in my initial response I confused the Glock 28 which is the sub-compact with the Glock 25 which is the .380 the size of a Glock 19, and the gun that I always thought was kinda cool.

I have seen that only wolff gunspring makes a recoil assembly for mini-glock and they have a RP 14lbs assembly, i e-mailed them to know if they make (or can advice)a lower value spring but got no reply.

Meanwhile i'm waiting for a reduced power striker spring, now to buy firearms parts from US is quite difficult.

G25 and G28 are rare in Italy too, as already told you i bought it just to train for free with something similar the G17 and G22 already use, pheraps the G25 could be a better idea but i already own a mid-size G32 and like the idea to have mini-glock.

Thank you again for your help.
