Elite SC w/ Glompensator small problem

Recently saw the Rex Silentium Glompensator on a different model Canik and not looking into dimensions decided I'd throw it on my SC anyways. Problem is without a massive gap, the comp hits against the end of the recoil spring assembly.

Could I file down and flatten a portion of the end (see last pic) to give the comp clearance when the slide racks back? I'd hate to grind down the comp or not use it, but I'd hate even more to need to replace a butchered part and not use the gun lol.

It's my first handgun and my expertise is limited to lurking in this sub, so any help or alternatives would be great.
