OK, I ended up going with the Laser Ammo SureStrike system and interactive targets. I ordered 2 of the 9mm laser cartridges and 1 of the .380. I also ordered the 5 pack of electronic targets. The targets will take (so they say) 2-3 weeks to get; the 9mm cartridges came today.
In the ammo packet you get the laser round and a battery. I installed the battery and "dropped in" the cartridge into two guns, a Bersa 9mm and a Sig. Both have double strike capabilities (i.e., no manipulating the slide to reset the trigger). When the ammo is dropped in, my first reaction is that it was too thick, but then I realized that you need to give a little push to fully insert the round, otherwise it would be loose and not as accurate. There is no rim, so to remove, just lock the slide back and use the eraser end of a pencil down the barrel to nudge it out. I only test fired maybe 20 trigger pulls on each gun, but it worked great.
In reading reviews, it seemed like those that were having issues with failures, had it fail very early, so I am hopeful it is a good set. The reviews also suggested to have spare batteries as that is a weak link, and the directions said to remove the battery from the round when not in use. Easy to do.
I decided to go on line and order a replacement battery. I found a few places that had a 3-pack for sale (on Amazon), for about $13-$15 ($4.50-$5.00 per battery). Then, I read a battery review on Amazon that saved tons of money. He said that the "battery" is actually 3 batteries stacked together, and that there is no reason to not order the batteries in bulk. He provided a link for a 100 pack (enough for replacing 33 times), for about $10 delivered to your home. That saved well over $100.
When the trigger is pulled and the "primer" hit, the laser activates and it is a very bright red dot. So far, it is looking good. Very anxious to get the targets.
The picture shows the relative sizes of the cartridge and battery vis-à-vis a dime.
Here is a link to a video of the targets in action.
