I just picked up my 3.6” 2.0 from FFL yesterday. The short: I love it. I managed to put 140 rounds through it before the storm hit. No issues at all. I only added some lube to the slide rails when I unboxed it and am planning on doing the 2k round challenge. The difference in size between it and my G26.4 with a Pearce +2 is negligible at best. Gun shot exceedingly well with factory sights. Percieved recoil was less with the 3.6” vs my G26.4 and I really preferred (subjective) the trigger over my G17.5.
Wife shot the best she ever has with it, but still liked the G26.4 due to the texture being too rough for her. Didn’t bother me and I actually liked the rougher texture. Now to find a 3.6” specific holster as I see this being my new EDC shortly.
