As per the above comments, Mike, I'd stick with the 30.
This also gives you the option of the Rekord trigger on the 'S' version.
I've never owned a 25, but they're rinky-dinky small. Plus, although I've never explored one, I'm pretty sure that I've seen people on here say that they're very tricky to strip? Something to do with no obvious way of removing the end block and spring? I know, it sounds most odd and very hard to believe, but others have looked and not I, so without that "hands on experience" it's tough to say.
