I did some messing with pieces today. Took the Crimson Trace green laser off the G45 and slapped it on a 19X. This laser continues to impress me. Think it would be perfect on a red dot gun. Here is some shooting just before dark — ten shots to a 3x5 at 7 yards, and five shots to a one inch square. No holster yet.
Put a DP Pro on the 19 MOS upper and put it on the G45 bottom. Like this combination a lot!
Note the Magpul Daka medium size bag in the photo — easily holds 400 rounds of 9mm and the best $22 I have spent on Amazon lately.
My wife was shooting her G5 17 and the 19X, and feels like the 19X shoots slightly flatter for her. Here is a screenshot from just before dark tonight.
