I have no problem with magazine disconnect in general. On the Bersa 380 Thunder it is well thought out and actually disengages the trigger. For years, I owned a Browing Hi-power and just polished the magazine disconnect. The Ruger SRc is a different matter. If you dry snap the SRc with the magazine removed you will damage the magazine disconnect and/or striker in short order. Check page 19 of your manual. If this happens your pistol will fail to fire and must be fixed, usually by a vacation and spa treatment at the Ruger plant in Prescott, AZ. I know this because because I had a SR40c that was damaged and got the free spa treatment. When it came back, the trigger pull was very different but fired every time and still was plenty accurate.
Removal of the magazine disconnect just makes the pistol able to be fired with the magazine removed like most other pistols such as the Glock, Ruger P Series, Sig P Series, or 1911.
