I have used a maccari spring on its own. I wasn't expecting much change, and I wasn't disappointed- it was an exceptionally tight fit on the standard guide and made no difference whatsoever to the pistol's performance.

Will be keen to see how you get on with a tinbum guide. If the maccari spring is as tight on the tinbum plastic guide as it was on my standard steel guide I think I would worry about the risk of breaking the guide. You might want a standard spring available so you can make a choice when disassembled and you have all the pieces to inspect.
