I'll post this here because it is the only forum I go to. I have always wanted G31 velocities, but carry G32's and G23's. While searching Lone Wolf I found extended barrels for G32's that are 4.5" long. It does not look bad and since I carry in a Milt Sparks IWB VM2, it does not matter there. However, I was somewhat shocked by the velocity increase. I'll just list some: Corbon 125 JHP 1,380 to 1,430; Speer 125 GD 1,375 to 1,415+; Old Buffalo Bore 125 gr. GD 1,450 to 1,515; HST 125 gr 1,360 to 1,410. This almost seems like a no brainer, but I have read some unfavorable comments on LW barrels with no real specifics. The price is low, accuracy is about the same as KKM or factory and I have not had a reliability issue. If you are aware of any issue, please let me know because I am carrying my G32 with the 4.5" barrel now.
