I love my Hi-Point 4095ts.
No purple.
The Sig MPX is by far, my favorite. I have, or have had, HK UMP, MP5 (clone), Colt 9mm, Kriss Vector, and CZ Scorpion. All are very solid guns, and a blast to shoot.
For AR guns, I prefer Colt pattern mags, over Glock pattern. Large Glock mags are cheaper, but are a pain to load.
The UMP was my favorite until the MPX. It's very accurate and a joy to shoot. The biggest down side to it, is the cost. Everything about it is expensive. Since HK quit making the USC, the prices have gone steadily up. The conversion parts are pricey, and so are the mags.What did you think of the UMP? I have been thinking about getting one for a long time now.
