Walter GSP

Any benefit of GSP over a Hammerli 215 seems like those are the pistols in my budget and is there any vintage of GSP that is better than others?

The older all black ones are heavier than the new GSP experts with the poly frame. They are nice to shoot. Hardly move during sustained fire. They also hardly every jam or break. IF you find an older one with the "expert trigger" it had the trigger coming out from the back of the trigger guard not the bottom. That trigger it really adjustable and very nice.  

The one downside to the GSP is that the optic rail goes where the rear sight is. People have installed a rail in front of the rear sight so they can still use the irons with just removing the dot.

OK so if I can get a black one with 2 barrels and the expert trigger I should be set for BE and EIC?

Look for the later black model with big Morini grips and a square magwell, those will adapt to 32, just in case you need a hair pulling challenge.

I think a scope could be mounted on the barrel but l haven't seen anyone do it.

The receiver is thin and shouldn't be drilled.

I bought a 22/32 combo this summer as it was a really good deal. My excuse was to shoot it for rimfire distinguished, and I did... three matches I think, and I'm done. The 32 has been MUCH more fun to shoot than I ever imagined. I shoot both with open sights, but am looking at making a better scope mount that holds scopes lower, but still stable with no drilling...

There is a way to adjust the clamping force and if the upper doesn't fit you might be able to open it up just a bit easily.

For reliability, price, and availability of parts and accessories, the gsp is a very good gun.

The GSP is a great iron sight gun for international standard, sport, center fire, and rapid fire pistol. I put up a lot of big numbers with guns from the GSP/OSP line when I was younger.

Some of those big numbers were retired; some still stand.

Haven't tried to put a dot on one, but I shot in the 880s with my .22 GSP and the 870s with my .32 GSP with iron sights.

YMMV

I also like the GSP very much. I have the newer Expert model. These have the rear sight back a bit farther on the frame compared to the older models. I mounted a sight rail on the flat just ahead of the rear sight. It allows me to mount and remove a dot sight without loosing zero. I love shooting it with irons. It will be interesting to see what Rob comes up with for a scope mount!
