Looks good... I am a pistol shooter, I had a veles, so my 2 cents, speaking from experience..
I may be interested, if:
it is low weight, veles was good
it is low noise, so include ldc
it needs to be powerful, say 18-20 footpounds (mine was .22 and i would go for that or a .20)
it needs to be frugal, say 18-20 shots (multishot is definately good)
and finally... weight is important, and many pistolshooters dont want/need an optic, so make sure you have an option for regular high quality iron sights....

regards, Mike
