Gene,
Sorry for the delay answering ( I just got my HAM ticket and had a call to respond to...)
About that 131: You'll likely have a 600+/-fps rifle that's easy to cock and will surely suprise you with it's accuracy (with the right Pell). Mine all love the Gamo Match pellet.
The rifle will accept one of the " Charlie trick Triggers" and get you an additional accuracy edge too.
The little rifles are tough as nails and most give little to no troubles, EVER!
Please note though that this rifle probablly would be a poor chioce for hunting, as it's power is truely borderline. If you're after a pleasant all day informal Target shooter and plinker, then it's a good gun.
I don't know how many rifles you have, but most shooters consider such a Target/Plinker as a secondary gun, having already set up with a hunting velocity rifle first...
I gotta hand it to Gamo, these inexpensive and durable models are a real pleasuer to shoot and whenever I take mine out, the pellet tin emptys pretty fast. Seems I just keep reloading!
Check the sale price against other comparitive Gamo models and IF it seems to have remained reasonable, I cannot see any reason not to buy it. The picture you have presents a pretty nice rifle.
The good thing about 131's is that many owners do sell very good specimins due to wanting to upgrade and ya usually get good deals.
Good luck making your decision and if you purchas it, you'll see what I mean about "reloading" it a lot and burning up the pellets!
