Well I got a deal on a Lone Wolf Dist. 9x25Dillon conversion barrel for my G-29.

The barrel fit is great, chamber is good and tight(I'll have to give it a test to see if it is too tight) but it should provide for functional shooting. I'll be loading a few to run some more test, hopefully the weather will get a little cooler soon!
I really thing the longer barrels would be a better option for this caliber, but with some time and development I maybe able to dial something in for this shorter barrel(3.78" stock length)
Wish me luck!
