    I've wanted to upgrade one of my carry pistols to red dot optics, and this factory item appeared as the most cost-effective way for me to do so. This high-quality genuine Springfield replacement slide has brought a whole new life to my XD9 that I bought 25 years ago after a dealer showed me that it was more ergonomical than a Glock. With the correct adapter plate, it mates perfectly to my Holosun 507c X2, and the test-fire session went well. The optic allows me the most rapid sight picture acquisition, and the shot groups achieved from a bench are the tightest I have ever achieved with a 9mm carry gun. The extra high profile iron sights are perfect for backup in the event of optic or battery failure, and with only a tiny bit of filing the whole rig will fit and draw perfectly from the original Springfield paddle holster. I am thrilled that I didn't have to buy another gun or spend a fortune on a custom-milled slide, and the price-point was very friendly. I just wish the correct mounting plate had been included originally and that I didn't have to spend extra to obtain the correct plate (but it was worth it). Buyer be advised to make sure that you obtain the correct plate (the illustration suggests that two plates are included but if you read the text carefully you realize that only one is included, and then you have to figure out if it is the right or wrong plate).

    Slide Assembly + Crimson Trace

    Posted by Jose on Dec 31st 2023

    I wanted a gun with a red dot and I saw this set up at a gun range where I usually shoot. After some research I decided to get an XD and got the slide assembly with the crimson trace. This is my first red dot set up. I took it to the range 2 days ago (11/29) and after 10 rnds and some adjustments I was hitting tight grouping at 5 and 7 yds. This set up is AWESOME…..The ergonomic on the XD is great and the recoil is very manageable. The next day I took both my sons (15 & 19 yrs old)to the range to try it and they enjoyed shooting the XD. They were hitting bullseye at 7 yds. even if they only visit the range twice a year. Did not expect my first experience with red dot to be this easy. Great job Springfield Armory. Did I mention that I got the gear up package as well? 3 mags and a range bag?

    Easy assembly. Co-witnesses just fine. I have this slide combo on both of my XD's.

    XD osp 9MM conversion from XD40

    Posted by Robert on Oct 2nd 2023

    Although the kit came without instructions or the "HOW TO'S" I am very mechanically inclined and watched a You TubeVideo and installed the Red Dot but have not had a chance to shoot it. I have emailed Springfield and Crimson Trace for the How To Instructions and that is why I rated it at 4.

    XD Conversion

    Posted by John woodside on Sep 23rd 2023

    I bought the slide assembly with the Crimson Trace. I’ve had mine for a couple of months, everything preformed as it should, I enjoy taking it to the range. Wish I had to option of selecting a threaded as part of the package.
