    Worth Every Penny

    I bought the OSP slide kit with the slide and barrel assembly. Then, I purchased a plate to slap on a Shield pattern red dot. As a consequence, my now 10 year old XD 40 feels like a modern mini race gun with the enhanced trigger kit from Springfield. I also like that the conversion is to 9MM. I would recommend this product to any owner of an older XD 9 or XD 40. Also, the website indicates that you need new magazines when converting from a 40 caliber. However, I can confirm that I used my 40 caliber magazines to load and shoot 9MM with zero, and I mean zero issues.

    Won't work in my Viridian holster

    Posted by Peter Hansen on May 4th 2023

    This new slide and optic look real nice but due to the taller front sight, it seems like you will need to shell out more dough for a holster that will accept the front sight. Nowhere on Springfield site did they mention that. Not to happy about that!

    9mm conversion

    Posted by ABad Person on Feb 1st 2023

    This is direct swap with the .357 sig XD and only required the purchase of 9mm magazines to complete. Only 4 stars for the red dot being plastic... its my first red dot on a pistol but it feels fragile. I've only had about 100rds through the kit but I haven't had a malfunction yet(extended mags and standard length used).

    Living in California, these kits are a dream come true. I was contemplating getting an add on red dot sight plate that fits in the rear sight slot, thinking that it seemed a little bulky and not quite the professional look that I wanted. Just as I was about to try one of these add on plate systems, the OSP kits from Springfield became available. As I am getting older, the addition of a dot sight has really helped my accuracy. I am an avid Springfield collector and hope that the Springfield team, has found these kits, to be a viable product for their other models. I would like to see the kits become available for my XD45 and XD9 subcompact in 2023. Hopefully there is enough feedback by others to show that these kits would sell.

    Awesome upgrade for XD but.

    Awesome upgrade to your existing upgrade from your stock and old look. I opened the box found no documentation on Torque specs on slide screws and plates done more inspections on new slide kit found the barrel had some scratches at the crown kinda look like it been dropped, I was kinda disappointed on the care of packaging but anyways, I took the new slide kit to the range and it was on point, awesome upgrade for this product. Thank you Springfield to bring something like this it market

    Osp slide .40 conversion to 9mm

    Posted by Bob Fitzpatrick on Jan 7th 2023

    Was shipped rapidly. Arrived as described; flawless fit. Works great. No issues. I have an original XD.40 and now I have options of 9mm. The suppressor height sights look good and co-witness with no issues. Slide is very smooth like it’s always been thereand broke in feel. Took less than a minute to change calibers. Shot about 150rds through it and it ate every round of 124grn Blazer.
