I'm looking to trade my customized Glock 21 (Gen. 3), for a Smith & Wesson M&P .45 (full-size, no thumb safety). My G21 has had a complete (35 cent) trigger job, as well as a Glock 3.5 connector installed. I have pretty much removed the ill-fitting fingergrooves, and undercut the trigger guard. I have installed (Lone Wolf) extended slide stop and extended slide lock. There is a Wolff stainless captured guide rod with Wolff spring. This pistol comes with 4 Glock 13 round magazines, and the Glock box, and everything that comes in the box. The stock sights have been replaced with XS Big Dot Night Sight for the front, and Aro-Tek Aro-Site 2 dot rear sight. I have installed a Grip Force Adapter. All of the original parts are included. If interested in a trade, please email me, and I'll get back with you promptly. Note, that the M&P .45 is the ONLY trade that I'm looking for, and I'm NOT looking to sell.
