Congratulation on your New/Enhanced M69. My favorite handgun platform. Have several of each barrel length (always worried about S&W discontinuing models). Have had both since they were originally introduced.
My current favorite is the 2 3/4". Went back over my records last night and have right at 6,000 rnds thru 3 different guns. All but a 100 (.44 special equiv) have been full .44 magnums. Mine are equipped with the Hogue 500 X frame grips (can't do wood due to conflict with the bone at the base of my thumb).
Here's my carry gun:
Been foolin' around with small red dots -- here's my range gun (still fits in the back pocket of my carharts). Raptor Eng mount and Leupold Delta Point - hate the look, love the results.
Shoot these a couple of times a week and always go home wishing I'd brought more ammo -- can't get enough of these little guns.
FWIW,
Paul
