A. Incorporating both a pistol grip and a reduced length-of-pull, the Mesa Tactical Urbino Pistol Grip Stock for the Beretta 1301 fosters quick handling in close-quarters conditions. The comb contains an adjustable cheek riser that allows for proper eye alignment with iron sights and optics. There’s even a built-in Limbsaver buttpad that offers enhanced recoil reduction. MSRP: $170; mesatactical.com
B. The SureFire DSF-500/590 Weaponlight replaces the factory forearm of the popular Mossberg platform with one containing a built-in, high-intensity LED. Large, tactile momentary- and constant-on switches are located on each side to facilitate easy ambidextrous use. Pressing the output-mode-selector switch toggles the LED between 600- or 200-lumen illumination. MSRP: $395; surefire.com
C. Weighing a mere 9 ounces, the TacStar Mossberg 930 Sidesaddle keeps six extra 12-gauge shells conveniently close at hand. The modular shell carrier attaches to an aluminum mounting plate that installs easily on the shotgun receiver via the included mounting hardware, with no gunsmithing required. MSRP: $41.98; tacstar.com
D. Combining a robust, winged ghost-ring rear sight with the company’s popular standard tritium dot, XS Sights Systems’ Win 1300 Defender - Tactical Ghost-Ring Sight Set - Standard Dot Tritium Front/Winged Rear offers a sight picture that is ultrafast to acquire at close range, but still capable of precision accuracy in varying light conditions and at intermediate distances that typically require slugs. MSRP: $160 (complete set); xssights.com
E. Featuring a blued-steel tube to make your scattergun more capacious, Carlson’s Mossberg 930 Shotgun Magazine Extension is threaded on the end to replace the magazine cap and increase the total number of shells to either eight or 10 (depending on the model). A high-visibility follower aids loading/topping off the tube in low-light conditions. MSRP: $60.95 to 63.95; choketube.com
