I own several 1911 in almost every caliber and barrel length. I could not believe the fit like it was made for my firearms. I also own a couple of revolvers and the fit was fine. I would recommend to other firearm collectors.
Years ago I attempted to do a perfect cut out in the foam for a camera case . I figured that since I am a surgeon and I was using a sharp scalpel it would be no big deal. Well , it was a big deal and the result was a big disappointment , cosmetically , but it did function . Nothing equals a Pelican case for protection , but I knew that I would not be satisfied with the system if the foam did not look as professional as the M4 and the Pelican case. Then , I discovered Cobra . I thought that this is too good to be true. Well, I can testify that the final result is what they say it is . The foam is "sculptured" beautifully for my M4 , making a perfectionist like me very happy.
I tried to make one myself and that was a mistake! Just buy it and get it over with. This works so well for my numerous hand guns and accessories.
I bought the ready available 1-1/2" replacement bottom foam piece for my 2 rifle Plano case to replace the 2 pieces of 3/4" foam with the pick away top layer.
I wanted to pack two different rifles in my case so this was the perfect option for me. My case is only a year old so this was a cost effective option ($32) instead of buying another case, and no longer dedicated to just two rifles. The piece from Cobra is a perfect fit and even had the 1/2" notch in it for the plastic boss on the edge in the middle. It secures rifles plus accessories better than before as I had picked away so much foam there wasn't much left for support. The fact that Cobra can do custom cut foam is obviously bonus. In all fairness to Plano they do have cases this way but nice to know you can customize any case or get replacement foam for an existing one.
I haven't used it yet but the two pistols I'm taking seem to fit. I just hope my rear sights on my two pistols don't cut thru the foam from the great pressure there is when lid is closed.
