I not only agree, I've also removed the pinky finger extension from my 10 round mag... just don't need it.For most designs, I would say this is true, but I think the SR9/SR9C is a bit of an exception. I would personally recommend the SR9C over the SR9 as a range/HD gun.
The reason for this is that the SR9C has a nicer (smoother & crisper) trigger than the SR9 (at least as of early 2011). Every range report I've seen has indicated that the SR9C is every bit as accurate as the full-size SR9 (apparently the lack of a little bit of sight radius is offset by the better trigger feel), and for HD and range work, the SR9C can accept the full-size pistol's 17-rd magazine (and benefit from the longer grip length).
You also get the added benefit of a pistol that is much easier to carry concealed if you eventually decide to use it for such.
The SR9c is the best of both worlds (compact/full-size) of any pistol I've handled.
