I use my 22lb spring with my S&W 1006 & Bar_Sto 40S&W conversion barrel with my hand loads. Also use my G-29 with the 21lb spring set and the wolff recoil non captured rod with my Storm Lake 40S&W conversion barrels.
I have had no issues with either of the guns changing form 10mm or 40S&W using these springs.
