How's gunplay in VR without a gun-shaped thing to hold?

It's pretty good on index controllers with an index headset. My biggest issue is not being able to hold the gun steady enough to aim at distant targets. It's worse in in-to-the-radius bc you're shooting at featureless black shadow people from a distance and you have limited ammo so you can't just spray and hope for hits. It works well in other games though. If you want more stable aim there are bunch of adjustable "VR Stocks" you can get but the price varies from "print it yourself/at the library" to like 200$ for the really fancy ones.
