Other firearms brands may carry more rounds, but Rugers handle hotter loads and if you are a good shooter you do not need more than 7-rounds. If you do, Damm you are a bad shot!
As for Rugers jamming that is real rare. Either the operator does not take care of the firearm, does not maintain the firearm or bought-it use and does not know what the previous owner did with that firearm, or it is a lemon. But all brands, models, and calibers have a few lemons in the bunch.
I Have shot this many rounds in Rugers and Taurus:
Ruger P-90T=7550rds
Ruger P-944T=2150rds
Still waiting on the Ruger KP-97 and the Ruger P-95, Damm waiting periods.
Taurus PT-111 "Millenium" 2nd edition, I have shot 2400rds with no malfunction, the clip broke tho(And it was a Mec-gar).
As for Berreta my father owns the old 9mm and the new elite. Both 9mm's broke, the old nine broke (three-times) after +2000rds and the elite broke (once) after +4000rds. It has always been the same problem the front slide ring, it is just too fragile in that area. And they said that the elite had a stronger front slide. Com'on! But I still like the Berretas and other firearms. I wish I had a collectible Caspian firearm that had a 20rd. magazine of 38special and the magazine did not even stick-out of the frame. But my all out favorite firearm is my ChiCom 1965 Parkerize SKS, I have shot +16cases of 7.62X39mm ammo with no rifle malfunction.
As for Rugers they are good firearms. No firearm is excellent, well not yet anyways. My recomendations are as follow: Have big hands P-89 to P-94, got smaller hands P-95 to P-97. I am still waiting on the Ruger .40 synthetic frame model. Later.
