9mm Glock Rounds


November 2, 2010, 12:04 PM
I have a glock 17 that I just picked up the other day for plinking and maybe for future competiton shooting.

The options on the gun are as follows:

2lb trigger
All springs replaced with wolf
Magwell with brass insert
Lone Wolf Barrel with compensator
Aftermarkert sights (soon to be replaced with a red dot)

I not really sure what kind of ammo I should be shooting with this gun. I do currently reload and I want to produce a round that has the lowest amount of recoil possible so that I can get back on target faster. I shot a .45acp 1911 one time that had alot of the same type of options and it had recoil like a .22 with reloaded ammo. I want to achieve the same type of results but I dont know if producing a low powered round would work better or a higher powered with more gases to make the compensator work better.

I know this is kind of a reloading question but it seemed that competition shooters would have more information on the subject.

Are you trying to make power factor, if so what? That magwell and comp are not legal in USPSA limited or production division. Add and optic and you could havea limited gun. Maybe you are going to shoot a local outlaw match where anything is allowed?

Anyway, what reloads to shoot depend on what competition you are entering. What do you intend to compete in?

Not really sure what competition shooting I would like to do other than shooting at steel at the local range or against friends at the ranch.

Buy some factory ammo and start from there.

I doubt that "compensator" is very effective, if at all, so the load choice really doesn't matter much if you're trying to get the most out of that "comp."

If it IS effective, then the lighter bullets at higher speed work best.

Otherwise, I'd shoot 147 FMJ's at about 850 fps for minimal kick.

That is the information that I needed. Thanks!!!

147s at 850fps (or just over) is typically the recipe for low recoil in IDPA SSP/ESP where 125k power factor (mass times velocity) is a requirement. I don't know what USPSA mandates for ammo in its different divisions. Your gun as configured is not an IDPA gun, so you probably need to look to the "racy-er" tiers of USPSA if you want to shoot that gun in sanctioned competition.

You have to know the rules of what you plan to shoot to get a good answer. If you just want the lowest possible recoil and are not worried about the rules of any sanctioning body, then you can probably drop the velocity and spring weight much further.

Not sure where you are getting your data on the poundage on the trigger pull???


MY Glocks shoot it all... They function flawlessly always...had one problem with an 1988 very early mag but that is it...Had nothing to do with feeding or firing...staying back on last shot was the problem...


The factory standard two-stage trigger has a trigger travel of 12.5 mm (0.5 in) and is rated at 25 N (5.6 lbf), but by using a modified connector it can be increased to 35 N (7.9 lbf) or lowered to 20 N (4.5 lbf). In response to a request made by American law enforcement agencies for a two-stage trigger with increased trigger pull, Glock introduced the NY1 (New York) trigger module, which features a flat spring in a plastic housing that replaces the trigger bar's standard coil spring. This trigger modification is available in two versions: NY1 and NY2 that are rated at 25 N (5.6 lbf) to 40 N (9.0 lbf) and 32 N (7.2 lbf) to 50 N (11.2 lbf) respectively, which require approximately 20 N (4.5 lbf) to 30 N (6.7 lbf) of force to disengage the safeties and another 10 N (2.2 lbf) to 20 N (4.5 lbf) in the second stage to fire a shot.

Trigger pull weight was abtained by replacing all trigger springs to reduced power, race connector and trigger, and a modified firing pin spring.

The only problem i have ever had with glocks is dont buy aftermarket mags

Ok, but I can not find Wolf springs that will reduce to that poundage, I was thinking about a lighter pull myself :confused:

You mention all springs are Wolf:confused:

USPSA minor power factor is 125, major 165.

If you are shooting informal matches, then it is all personal preference. Some fast folks don't like 147s since sight recovery is longer. They prefer the snappier recoil of 115s or 125s.

It is all up to you.

I put a 3.5# Ghost kit in a 34. 4# firing pin/striker spring. 6# trigger spring. Reduced power firing pin safety spring. Lots of polishing. Pretravel still there but almost no resistance and a resulting 2.2# trigger.

That is basicly what has been done to this gun.

And there is no way to get around the pretravel without removing the trigger safety and I wont recomend that!!!

Thanks for the information..

I changed my recoil springs when going with the lighter bullet especially in the .357 SIG loadings of 80gr frag stuff...

Hi velocity but light bullet, moving slide/bolt was a problem, then the fine line of feeding on the return with the lighter spring... Feeding the 357 is a breeze because it is a bottle neck cart...:)

So I would go with loading a round weight and cost, with powder you like cost again, at velocity etc., and tuning the springs to it (loading) :)

The brass is going to be good for a lot of shooting at the lighter loads similar to the low pressures of the 45 acp... Crimp is important also in pressure etc...All a huge case of harmony with many issues not just the bullet weight... Barrel being longer like the 17L is good for reloading lead for cheap and not using a factory one...

Now the 19, 4th gen comes out with a stiffer set up regarding the springs:confused:

If you read the notable forums, they shoot heavy bullet with light springs. They have found that starting the heavy bullet results in a softer start if the recoil/action spring does not resist the momentum of the slide. They use 13# recoil/action springs with the 147. I recently joined IDPA and USPSA and will get up the nerve to go shoot at Caswell Ranch soon.
I have stated before I would not carry the 34 with the way it is setup but if I can learn to ride the reset it should do OK.

The info is again appreciated...I'll have to read up more on it, really not into the competition of it...Just my own experience... Old 17L (1988) that is really a good shooter, gone through by Glock a while back...
