Recently purchased a Smith & Wesson 3.1" bbl Shield "Plus" Optic Ready pistol.
I live near Apex Tactical in Phoenix, AZ and dropped by their place (with an appointment) and they installed one of their triggers in it in about 10 minutes.
I then purchased and installed a Shield RMSc 4 MOA optic on it.
Prior to installation of the Apex trigger, pull weight was a slightly spongy 4 lb. 13 oz. Now it is a much cleaner, crisper break at 4 lb. 1 oz.
I bore sighted the pistol in my RV garage at a measured 15 yards using my Wheeler Engineering laser bore sighter.
Took it to the range this morning for its maiden voyage.
Shooting at the head box of an IDPA target at a measured 15 yards, I shot 5 shots each of:
Aguila 124 gr. FMJ
Remington 124 gr. BJHP
Speer 124 gr. JHP
Shooting done from standing unsupported, slowly, and deliberately.
All 15 rounds went into the the "Down 0" area of the head box and the group was well-centered. Zero adjustments made to the optic.
Initial impressions of the pistol, trigger, optic, and laser bore sighter are quite positive.
Shot an additional 80 rounds of the above mentioned FMJ factory ammo and some of my handloads of Montana Gold 124 gr. JHP bullets over 4.1 grains of Titegroup in various drills from a JMCK Wing Claw 2.5 AIWB holster, including some SH and WH unsupported shooting. Also used both 10-round and 13-round S&W OEM magazines. Experienced zero malfunctions with the pistol, ammo, or optic.
This is a nifty little pistol/optic/holster setup! Looking forward to how it fares with more time and use.
