I figured that this would be the correct place to post this, so here we go. My front sight fell off my MK IV during a game a lil while back and I don't really know how to go about correcting this problem without buying a new slide all together. Can you buy front sights somewhere or will I just have to rig something together?
Are you talking about a KWA 1911 MK IV? Or something else?
If you are talking about a KWA 1991 MK IV you can order replacement parts from the KWA pro shop. Just click on the parts diagram for your pistol on the right hand side, find the part number for the part you are looking for, then type it in the search bar. Being able to buy individual factory replacement parts kicks ass.
If KWA does not have the part listed on their site, all you have to do is give them a call and tell them you would like to speak with someone about ordering parts for your gun. Then, they will simply ask for the part number. I recently had to rebuild a MKII. All they had were MKIV slides so I had to order a new front and rear site as well as the slide. Also just ordered a new gas seal for my magazine. KWA is very nice to work with and will help you out.
I hope this helps you and anyone else curious about ordering parts from KWA.
