Guarder Steel Slide Lock for Elite Force / UMAREX GLOCK, ISSC M22, SAI BLU, Lonewolf, & Compatible Airsoft Gas Blowback Pistols (Color: Black)

"I filed in a slight channel so it would catch my barrel lug since I installed into a real steel polymer 80 build, it held up for about 50 rounds before to my surprise it snapped, it seemed strong enough but I may have filed a bit too deep, overall I still give it good rating, I liked how thick it was compared to an OEM slide lock...

"A bit pricey for such a small piece, but is a bit larger in all dimensions and feels like much sturdier material than the stock part. I find it far easier to actuate compared with the stock Umarex Glock 19x. Would recommend if you're having trouble with rapid disassembly

"Fits my KJW G26/27 without issue. Perfect.
