It's expensive (less than buying a new gun) but you could convert your Shield or Glock 43 mags with Magguts that would add +1 or +2 to your magazines.

The Shield 8 round mag would only be a 1/4" longer with the 8 round magazine and you'd get a 10+1 capacity in your gun.

I'm thinking about biting the bullet and doing the +2 for both of my Shield mags.

Also, have you looked at the Glock 26 Gen 5 with the smallest grip option? Could be something to consider.

The advice you received about renting as many guns as you can is the best advice.
