I'm an LEO and carry a P320 professional series with a Wilson combat grip and the sig Romeo 1pro dot. I've had problems in extreme weather (rain and snow) with my dot washing out. I'm thinking of getting an enclosed dot now. My other problem with my current setup is this gun feels top-heavy and unbalanced in my hand. I shoot it well and am very proficient with it, but I think I could get something better.
The other day, I picked up an X Carry Legion and loved the way it felt. The barrel length was the same (as it sticks out from the slide for a suppressor), so I'm assuming I'm not losing anything in terms of velocity (it probably wouldn't be a big difference anyway). I want to keep the irons and put a halosun 509 on it. Here are my main concerns:
1) Is it worth getting this gun or should I just get a higher-end grip model for my current gun?
2) How can I mount a halosun 509 on this handgun and have co-witnessing irons?
3) Does the legion have superior parts in it (slide, recoil spring, trigger, etc.)?
4) Are there better-enclosed dots for pistols on the market (or coming soon to the market)?
Thanks for the advice and thoughts.
