Well I ordered the Barrel for 60 bucks, they are 2 months backed up. and a lot more guys are doing it. It's just to have the ability to fire 9mm out of it. I did it to my glock 23 and it was a great idea.
You never know, I may save some money on practice rounds, and if 40's become scarce, "like now" I have another 9mm. single stack. The others are double stack. I will see how it fires with the 40 mag, if it has feeding problems the mags are cheap enough. I will just pick up a couple. As long as it's reliable otherwise, or I will just sell the barrel.
The Storm Lake people may be coming out with a conversion, but won't take an order yet, "lone wolf" told me to call em". So it seems like this is getting popular, as a conversion.
I like the size of the gun, and if I can get off cheap it's worth it for a few bucks.
