Converting .40 cal Glock 35 to 9mm
I just got a Lone Wolf 9mm conversion barrel for my new Glock 35 in .40 cal.
I did it because 9mm ammo is cheaper than .40 cal ammo. I have no plans to use the 9mm barrel for defensive use.
I also bought a couple of G17 magazines to use with the 9mm barrel.
So far, I've shot 50 rounds of M882 GI ball and 150 rnds of Winchester generic (white box) without any malfunctions.
I did not have to change the ejector or extractor.
Storm Lake and KKM precision also make conversion barrels. I don't personally know anybody who has used a Storm Lake barrel.
I know one guy who bought a KKM conversion barrel for a project, and his project gun never ran right, but it was a weird combination of a Glock 24 upper, an alloy frame, a KKM 9mm barrel and I don't know what all. Anyway, his project gun never did work properly for any period of time.
