So I walked into the gun shop/indoor range.  I was just going to send a couple hundred rounds through my G23.  Of course I had to look around the shop first...  Now I am the very happy owner of an Advantage Arms conversion unit for my G23!

I got on the firing line, swapped upper halves, loaded up with mini mags, and let 'er rip.  A few minor sight corrections and all was good.  200 rds with no bobbles or trouble at all.  Surprisingly accurate to boot.  I am very impressed with the quality of this unit.  I had also forgotten how much fun an accurate .22 can be.  You sure do get some funny looks when people see .22 brass flying out of a Glock, though.

.22 conversions are a blast.  I have used them on the 1911 and 92FS with great results.

I fail to see a negative consequence for your action.
