The Mossberg 510 Mini Super Bantam .410 Gauge w/18-1/2'' Barrel Shotgun is a great choice for first time shooters, or anyone who wants a lightweight shotgun. Mossberg's 510 Mini is Mossberg's most compact design ever and is arguably the world's smallest fully-functional pump action shotgun. This 410 guage has a 10-1/2'' - 11-1/2'' length of pull, measures just over 34'', and is extremely lightweight at only 5 lbs. Comes with a vent rib barrel, 3'' chamber, 2 + 1 capacity, fixed-mod choke, and an adjustable black synthetic stock. Dual bead sights. Blued finish.
This comes with a fixed choke modified cylinder barrel with dual bead sights. You can shoot slugs with it but it is a fairly narrow choke and accuracy can suffer slightly. Possible, yes. Advisable, not so much.
The 20 ga. version uses accu-set chokes and you can use the IC choke for decent slug use.
