Glock 357 barrels

[pdog]

I have a Glock 22 and 35, both .40 cal. but would like to change the 35 over to 357 Sig with a 5 1/2 inch ported barrel. I have seen several barrels, KKM, Bar-Sto, EFK tht appear the top choices I am looking at. They are listed as "drop-in". Has any one had any problems with any of these and what loads are you reloading?

I bought a Glock 32, compact 357 Sig. Added the 40 KKM bbl and it dropped right in. I had read that they are good bbls. It seems to work fine and the mags work with both (why shouldn't they?). Recently I heard that they KKM's are lousy bbls(?). I would bet that the Glock factory bbls are 100%. I wanted a regular rifled bbl in case I wanted to shoot lead so I was opted for a non Glock 40.
