Contact RallySoob@aol.com This slide stop release fits all springfield XD's and XDm's except for the XDm 45ACP. This is a $45 part on pistolgear.com and is made by their company. It has great reviews it just won't fit the XDm 45 model which I have. It allows the slide to lock back as it should while using 2 thumbs forward hold plus it is lower profile, looks better, less prone to snag. I will quick sell it for $25 or trade for some 45ACP or .223/5.56 ammo. Maybe trade for AR parts/mags...just PM me what you have I have included a link to the review on this part below; as posted on xdtalk. Also pictures of it installed on a XD vs a picture of the factory XD stop installed. Pistol Gear Slide Release Review - XDTalk Forums - Your XD/XD(m) Information Source!
