I guess I’m wondering if this a hypothetical question or a great question comparing two pistols that you are looking at, (or thinking about getting at some point,)?
Several of us here have recently got/found wonderful 4040PD examples for under $450.00 with everything. I’m pretty sure they originally cost more than that.
Brand new factory magazines are still readily available, flat and curved base plates, (@ $30.00, not Brownells,) and if you want the 3913/14 Delrin’s will fall right on.
