Had a chance to shoot 100 rounds with the M40 I picked up last week. When I got the gun I gave it a good scrub down and lubed it up good with my new favorite gun oil Blue Wonder Disotec. Everything functioned perfectly no FTF or FTE. Shot normal groups for my skill level and actually shot it a little better than my normal carry piece - Sig P229 SAS. Ammo used was: Winchester White Box FMJ 165gr 50 rounds American Eagle FMJ 155gr 50 rounds Overall I am extremely happy with this purchase and with a little more confidence building range time this may become my daily concealed carry choice.
