Is there proof that converting barrels cause malfunctions?

[Greg-Dawg]

Hi guys.

Say you have a Glock 22 .40S&W and later on bought a 9mm conversion barrel with Glock 17 mags.

You forget all about the .40 caliber and stuck with 9mm because you can buy more ammo at a cheaper price.

Does keeping your Glock 22 in 9mm cause problems in the long run?

Thanks.

Since it is a drop in barrel, the fit might not be perfect and the reliability may go down. The only way you will know if your particular replacement barrel will work well in your gun is if you shoot it alot with different types of ammo (or whatever ammo you plan to use for self defense) and see if it functions well...Go out and shoot it. Generally, drop in replacement barrel without custom fitting won't be as reliable as the factory barrel...but try yours out.

If you send your handgun in Barsto will fit conversion barrels for a nominal fee with a barrel purchase.

There are conversion barrel made for glocks that do just that. Do a search on Google and you will find them. As for issues with dropping to a 9mm, there are none really other then your gun might not be as reliable but if its just for range use I would not worry about it.

OP's asking about leaving the conversion permanently in place and not if it can be done or not.

I can't remember where i read it (maybe glocktalk), but i think you may get some tiny percentage of FTEs w/ some conversion barrels. I dont think that it's damaging to the frame/slides, and esp w/ the 40, the chances of a kB may be decreased.

I don't know about Glocks because I haven't done such a thing with my Glock, but I have used a conversion slide, barrel, and magazines to allow my EAA Witness to shoot 10mm along with .45. There hasn't been any reliability issues, but do I have a stronger incentive to pick up every 10mm case over .45 brass.

Thanks for the responses guys. Specifically for Glocks, Lone Wolf has some conversion barrels. I'll let you guys know what they say. My question is leaning towards longevity. Also, I don't think switching them back and forth would cause any problems, but keeping the lower caliber barrel for a long time may?

Stick with Bar Sto or KKM for conversion barrels. The only issue I could think of would be the extractor not being "right" for 9mm in a .40 slide.

[elsolo]

The breech face will not be cut right, resulting in a comprimise location for the extractor and/or ejector relative to the case rim.
If I was going to spend the money on a Bar-Sto barrel, I would want the rest of the gun set up right, not as a general comprimise for the cartridge which might result in increased extraction or ejection problems.
