I have a Glock 34 9x19mm gen 4 that I will even trade for a GLOCK 20SF (Short Frame) 10mm. I have three 17 rnd magazines and would prefer three 10mm magazines in the trade, but not a deal breaker. Subject to bill of sale for the trade. 9mm has roughly 500 rnds through it. Text me if interested two eight one 808 two one one one.
