  • SIG P320F RX Cal-X kit

    Posted by Dave L. on Mar 18th 2019

    Overall, I'm very happy with the kit. Having to sign for it from FedEx can be a pain if they come by when you aren't home! Luckily they caught me on the second try.

    The description was accurate in that it says that it comes with high contrast sights, but the SIG box that it comes in has on it in two places that it comes with SIGlite Nite Sights. I have a feeling that the reason the cost is so much better than from the SIG store is because they must "dumb down" some kits a little, whether it's a SIG practice or a special order from a vendor. Also, the whole pistols sold with the Romeo1 are listed as being zeroed from the factory, but the sight in my kit certainly was not. Not even close.

    Luckily, it's super easy to adjust it and on a positive note, the irons were pretty much spot on.

    My first experience with a similar pistol was a recent rental at an indoor range but that was an X-Carry RX which I shot better than any other pistol I've ever fired. I think that I may get a full size X grip module with the high ride grip and see if I can duplicate that effort with this rig. I shoot OK with this, but that X-Carry was much better. I suppose that the straight trigger on the X-Carry may have helped as well.

    Great price, and the fact that they are in stock (at least in Full size) is a bonus. Well worth the money in my opinion.
