I'll give ya $500 for the Python!
My buddy has an FN PS90, you are right, those are pure fun to run. Problem is, when we take it we can hardly shoot it because everyone wants to look at it. He even takes extra ammo to sell to people who just hafta run a mag through it.
Heller of a collection you got going.
Yeah, 5.7mmx28 ammo is tricky to find. FN makes 5 versions; 3 available to civilians. I buy the SS198 (40 grain polymer tipped hollow point). You really have to search on ammo sites for deals on the 'net. It's very sparse right now and most are price gouging. FN prioritizes military contracts for weapons and ammo before the civi market. Which I completely understand. And Walmart doesn't carry it.

Thee are a few 5.7 ammo manufactures, like Elite Ammunition and High Desert Dog. But you couldn't pay me to use EA. Their ammo has blown up more FiveseveNs and messed up many PS90/P90. I will use HDD, but they are expensive and take about a month to get your ammo.
One of my buddies that I shoot with has a big chunk of land, so we don't have to deal with a range. We're in the middle of building a 600yd range at his place right now. Most difficult part is making a sufficient backstop. It's all wooded, so we can only get a skid-steer (Bob Cat) out there.
Although, I have taken it to the range. Someone asked to shoot it and the FiveseeN. He went through a box of ammo (50 rounds, about $25). He tossed me a $50! Score! Even my 'anti-gun' Mother enjoyed shooting it and the AR-15!

She's a pretty good shot, too.
I got a very good deal on that Python- $999. I usually see them between 13 and 15 hundred. It was obviously someone's safe queen. If you're familiar with revolvers, you know that they get that 'scratch ring' around the cylinder. This Python doesn't even have that. It' in absolutely
perfect condition. The grips have a git of wear, but I have a rubber Hogue grip I'm going to put on it tomorrow and a genuine Python grip set on it's way to me.
No way I would ever sell it. I'm looking for another, but a 2" so I can carry it.
I also have a S&W M&P360 5 shot .357Mag that I really enjoy carrying. I feel so classy with it.

Although I only conceal carry. No open carry in Texas. Even if there were, I would still CC.
Anyone else a card holder? What do y'all carry?
I also have an FFL 07, which is a gunsmith license. I mostly do sight installs, trigger jobs and sometimes build custom 1911s. But my main gig is glassblowing/flameworking.
