I need to get the parts to convert my V1 USP9 Fullsize to V3. As I understand it I need a different detent plate and control lever. Someone please educate me if I am wrong. I know I can get these parts on HKPARTS and will do so if needed but wanted to see if there was someone here who had a set not being used. Please contact me if you have the parts I need. I have tons of stuff here for trade or can send payment if we cant work a trade.
