Got a new Gx4 last week. first 50 rds 115 Gr target ball, and its snappy. Definite recoil training required. I have a 856 revolver and it kicks the same with 158Gr +p. Its more recoil than SIg P365, but ~less than Hellcat (yes i have all 3) i think. Bottom line..I will sell my SIG and Hellcat. I did experiment around as i have smallish hands and could not get more than 2 finger grip on it. I found that the Hogue Handall for a Glock 26 (model18600 i believe) fits it well and cuts bout half of the recoil issues. ..
