Does anyone know a supplier of Production-legal basepads and/or magazines for the 320X5?
(The 21-rounders do not fit the Production "box"...)
OP, to answer your question, I love my 320X5. My experience is limited so far, with only about 3 live firings and 2 months of dry firing, but was able to win Carry Optics at a small local match and shot an "A" classifier on El Prez with only two 100-round practice sessions (I'm currently not higher than B in any division). I have found it to be an easy gun to shoot, with minimal learning curve. My initial impressions are that I love the ergonomics, as you do. It feels like a lighter version of a 2011. The trigger is very useable, and I like the way it "breaks" at a position (for me) which is "90 degrees" (ie, I don't have to pull my fingertip back past the "180 line" to get the gun to go off). It should have been significantly lighter for a competition gun. My only disappointment has been that they didn't make the mag release stick out farther, like most competition guns; it isn't much bigger than the regular 320 model. I have managed to train around this with a lot of dry firing, but it still needs to be improved on future releases to feel like a real competition gun. It has the best recoil recovery of any polymer gun I've shot. It doesn't shoot as flat as my CZ, but it's pretty good and the ergonomics feel better, and I feel the trade-off is worth it at my current skill level (I prefer my first shot out of the holster not to be double-action, and the easy adaptability to Carry Optics is attractive).
I did have to lightly dremel out the rear of the optics recess, because I use Vortex Venom optics and they are just a wee bit long to fit into the recess as it comes from the factory. The bolts for the optics cover plate do have to be accessed from underneath the slide, requiring a field-strip. The rear sight plate goes back into place just fine after the dremel modification, and I plan to use it for both C/O and Production...as soon as I source some Production-legal magazines.
In short, I love the gun, and although it will never be as heavy as a CZ, the ergonomics are better for me. I think it will develop a following. If I continue to like it over the first few months of outdoor matches, I may buy a second one as a dryfire gun (it's potentially that good). I think SIG has a real winner here.
PS - as you probably already know, you will have to special-order a holster as nobody makes a standard item yet. I got a double-layer Kydex from Red Hill Tactical, and it seems ok for my needs.
