Well, I haven't shot it yet. I zeroed it with a laser boresighter yesterday evening when I mounted the EOtech (that way, I'll start out close on paper at 50 yards, and I can fine tune it at the range). But, I probably won't go shoot it until Christmas week. I have that week off, and I love going to the range on a weekday when they open. I always have the whole range outdoors to myself for 1-2 hours when I do that. That way, I can go downrange anytime I want to.
I have rented a 9mm Storm 2x in the past - but it was at a dark indoor range, and it's hard using those peep sights in a dark indoor range - especially when U are shooting at a black circle target. I have a feel for the gun, but I haven't tried one with an optic before.
Actually, I thought about getting the 40 cal version, since I plan to get a PX4 in 40 cal next year. But, the whole purpose of me buying this was to save on ammo costs - 9mm CCI Blazer is 1/3 the price of the 5.7x28mm ammo I use in my PS90.
I came across several 45 cal Storms actually - at various Academy sports shops. However, the downside to the 45 cal version is that U only have 8 round mags for it.
