Hi all,
I have recently completed a small Glock project: I bought a 20 slide, parts, barrel, etc, and put them all on my Glock 21 (which I bought with the intention of modifying it). The firing pin spring is a little light (4 lbs, as opposed to the standard 5 lbs), as that is what was available at the time I made the purchase. I have also bought a 9x25 Dillon barrel.
I have now tested out both barrels and have had a similar problem with both; there is an occasional trigger pull that does not result in the intended BANG! This is far more prevalent with the 10mm (shot up a box of PMC hardball range ammo) than with the 9x25 (used DoubleTap, 147 gr). In fact, with a loaded magazine of 10mm, half of the rounds tend not to fire. I reload the 4 to 6 that don't fire back into the magazine, and again about half of them fail to ignite on the next go-around. So then I put the two-or-so back into the mag, and then, third times a charm, they fire. So to shoot 10 rounds, I have to load the equivalent of about 17 rounds.
In the entire box of the 9x25, one cartridge just would not fire, but the problem is not quite as pronounced, usually with only one round per mag (on average) not firing. In the 10mm, all of them eventually went off, but the rate of failure was far higher; I had to pull the trigger probably 80 times or more to fire 50 shots. In any case, I am still disappointed with the results. So I thought I'd get some input from some gun-types, and see if any of you have had similar problems with Glocks that have had newbie modifications done to them.
I have a sneaking suspicion it might be a firing pin spring problem, or even a pin safety problem, but let me know what you guys think.
And for those who are curious, no, I am not a gun smith, or an experienced machinist. I am just a dude who wanted to try his hand at doing something he thought would be neat.
