Will it keep the same POI as my practice ammo?

POI varies by firearm and load. For 9mm, a lightweight training round such as 115gr will often track closer to EHP than 124/147gr practice loads. EHP is engineered for POI consistency and function across common barrel lengths and twist rates, but you should confirm POI and function in your pistol and test which training ammo best matches your setup.

Is this suitable for short-barrel pistols?

Yes. Because performance does not rely on an expansion window, EHP maintains consistent terminal behavior over a wide velocity band, including compact pistols.

How should I test before carry?

Run a function/POI check (e.g., 20–40 rounds) at your carry distances. Note feeding/ejection and where impacts print relative to your zero.

How does “barrier blind” apply here?

EHP is tested to perform consistently and with minimal deflection through common intermediate materials while maintaining the intended terminal effect. Always verify in your firearm.

Can I use EHP with compensated or ported barrels?

Generally yes. EHP is compatible with comps/ports. The 80gr EHP uses significantly more powder than heavier grain rounds which lead to the device having a greater effedct muzzle velocity and recoil impulse, which may shift POI and affect timing on some pistols. Verify function and POI in your setup, and keep ports/comp baffles clean to minimize copper fouling.
