Glock 22 Gen 2 barrel question

[Dokbrick]

Hello all,

Today I grabbed an excellent condition Glock 22 Gen 2 police trade in. I have read quite a bit about Glock issues with .40 SW Kabooms and all of that. My question is, seeing as Gen 2 seemed to have the most issues with kabooms, would replacing my barrel with a Lone Wolf barrel be a good idea (is the case better supported on these barrels?) or is it so unlikely that I shouldn't worry?

I will only be shooting factory loads (no boutique shop loads or reloads) and the occasional hollow points.

all semi auto pistols have some chamber ramp showing, including aftermarket barrels.

Glock barrels don't cause KBs. Glock barrels allow KBs to happen. KBs are caused by bullet setback when chambering, double charges, and defective cases.

Shooting factory ammo will minimize the chances of KB. Shooting reloads that you made yourself, carefully examining brass for defects/checking for correct case tension/checking the powder level/etc., will minimize the chances of KB.

I have found something shocking after getting the Redding GRX .40 push-through die. About 5% of my once fired brass goes into the trash. Why? Because the die allows me to detect casehead seperation before visible signs present themselves. When I push a case through that die I can feel the case being sized, but in a different way. I can feel the resistance build and then dissipate as the case goes through. On the 5% suspect cases, I can feel the resistance build, dissipate, then build again right above the extractor groove. This tells me the case is either too soft, too thin, or already fatigued to the point where it will wanna let go.

Now, those cases may be fine for one two or three more firings, but why take the chance? What if I get bullet setback next time? Will the case hold? It may not.

I've been using the GRX die for five reloading cycles now and found that once I get rid of the initial 5% defective cases the rest are good to go. I had to throw out one case out of 100 last night after five reloads. Same reason- fatigued at the casehead.

People claim that the .40 is a KBoomer. I think it is intolerant of mistakes. I haven't KBd anything. Been loading for 20 years. I even made .357 Sig cases out of .40 cases and ran them at .357 pressures.

Paying attention to details is what kept me safe.

Actually the .45acp is the most ofter KaBoomed caliber, but there are way more people loading for that and for much longer than the .40S&W. And all guns get blown up, not just Glocks. I witnessed 2 STI's blown up on the same day!
