Anyone using a .40cal conversion barrel in a Glock 29? Any comments as to how it shoots compared to 10mm and/or how reliable it is?
I have the Storm Lake since 2007 for my G-29 and it is very accurate and a tight chamber (maybe too tight). It shoots less than 4" groups at 30yards easily with many through the same hole. However, If it gets dirty or if ammo is not held to very close tolerances, it will start to show a failure to feeding fully. Cleaning it will let it run smoothly again and it gets better every time i shoot it. Velocities are higher than shooting the 40's from the factory barrel.
Some guys have had issues with the newer barrels from Storm Lake, with ragged truing cone areas.

How would you compare the recoil to average 10mm loads?
Well I load my 40's to upper levels but still 40S&W spec and recoil is less than my 10mm loadings using same bullets from each cartridge. If you look at the cartridges in the picture, you will see the two 10mm cartridges utilizing small pistol primers. :o
These are Federal NT (non toxic) cases where they use the no lead primers for LE that I re-loaded.
