Read all the threads. Bought it anyway. I understand the shell requirements and break in period. Utilization: Home defense by a lady, 5'2", 115lbs Mossberg SA-20 Bantam 20ga LOP - Short Youth Stock - Out of the box LOP is 12 5/8 inches. Vent Rib width is: .275" or 7.00mm using digital calipers at bead. Tapered Rib is wider at receiver .281" - 7.14mm. Weight unloaded (actual on postal scale): 6 lbs 0.6 oz 5 unlabeled choke tubes (notches only) with choke case. No choke wrench. Full, Improved Modified, Modified, Improved Cylinder, & Skeet. Questions: 1. With the gas system, can the stock be trimmed? I'd like to take it down to 12" and replace the pad with a decelerator pad for small frame family members. 2. Out of the box new, trigger pull is 6lbs 6oz to 6lbs 8oz (Lyman digital). I didn't see anybody discuss trigger work or springs replacement? I'd like to be at 4.0-4.5 lbs. trigger pull. 3. SA-20 Choke Tubes. Cross references says Benelli/Beretta 20 Gauge. Can anybody confirm this? 3. I'd like to add a rail & optic, but will start with a magnetic fiber optic front sight over the bead. Suggestions? Any suggestions?
