I would love to see any beretta pics of 1301s,
I've had mine for roughly 2 years now. Regardless, its a 1301 Comp with 24", I like it. Alot. I dont use it for official competition but I do a little with buddies in the back 40. Its great for clays. As an FYI the 21" model didnt/doesnt interest me at all, too short for my liking.
I've always been a raised rib fan along with a mid-bead, both are well suited to this model as far as I'm concerned. Shoulders for me right out of the box exactly as it should. Altho there's plenty of adjustment for fit if needed.
I wouldnt say its the softest shooter but it certainly aint bad, its no 1100 in that respect, my Maxus is softer as well, but again it aint bad. I've shot worse. Much worse.
Trigger wise, typical Beretta, meaning excellent. Nice and crisp, I'm guessing it to have 4 lbs (perhaps slighty less) pull. It has a large factory machined loading port which is nice and smooth.
The only mod I've done is to throw an old KickEez (grind to fit) pad on it, partly to further reduce recoil and also give me a tad more LOP.
Love it for carrying in the bush for partridge, bear baiting, backyard clay games, quite accurate at 50 yrds with 1 oz slugs too.
I cant recall exactly but I 'think' it only came with an IC flush fit choke. I did pick up an ext LM and IM HP chokes, the thing does everything I want/need it to do for quite abit less $ wise than the Pro model. AND (not to offend) its not blue.
Shell wise, no issues with 1 1/8, 1 oz and my reloaded 7/8 oz. Its been awhile but just for the halibut I think I ghost loaded it with 1 oz'rs a few times as well.
Hope this helps!
