New ish gun owner, need advice on what to get

Pulled the trigger and became a gun owner back in May 2025 when I saw the writing on the wall with the governor election. Currently I have the following, and have a ~$3-4000 budget for more stuff from a signing bonus for my new job.

1. PSA 16” 5.56 AR (9 mags)

2. PSA 8.5” 300 blackout pistol

3. Ruger RXM (2x 12 round, 5x15 round, 1x 21 round

4. Glock 40 Gen 4 (3x 15 round)

5. Keltec P32 (3x 7 round)

I’m thinking maybe a few more large mags for the Ruger and some standard AR mags. Everything else slides in with 15 rounds or less. As far as guns go I’m leaning maybe the new Keltec KP50. Also thinking about an AK, a third AR-15, and/or an AR-10. As far as pistols go, not much is on my radar. The Keltec PR57 seems neat. Also looking at a Beretta 92/M9, Sig P226, Sig P320 (range toy). If anyone has other recs that would be appreciated
