Here’s what to look at before you stock up:
Buy handgun ammunition online or visit our gun shop in Parker, Colorado to pick up loads in person. Iron Horse Armory also serves customers from nearby cities including Castle Rock, Franktown, Centennial, and Lone Tree.
Ammunition sales follow federal guidelines and applicable Colorado requirements, which can involve age verification and identification at the point of sale. Shipping timelines and carrier restrictions vary by product, so review checkout information carefully before placing your order.
Storage practices, transportation rules, and range protocols may differ based on circumstances. Contact the shop directly for clarification on purchase requirements, accepted identification, and current store policies.
9mm is among the most popular handgun calibers thanks to manageable recoil, wide ammo availability, and strong defensive performance. .45 ACP and .380 ACP are also common choices for carry and home defense.
No, ammunition must match the exact caliber and chambering stamped on your pistol or revolver. Using the wrong cartridge can damage the firearm or cause serious injury.
Full metal jacket rounds are designed for practice and tend to penetrate without expanding. Hollow points expand on impact, making them better suited for defensive use.
+P indicates the round is loaded to higher pressures than standard ammunition for increased velocity and energy. Only use +P ammo in firearms rated for it, since not all pistols are designed to handle the added pressure.
Keep ammunition in a cool, dry place away from temperature extremes and direct sunlight. Sealed containers help protect rounds from humidity and corrosion over time.
Some revolvers, like .357 Magnum models, can also fire .38 Special rounds safely. Always confirm cross-caliber compatibility with your specific revolver before mixing cartridges.
Common defensive loads in 9mm range from 115 to 147 grain, while .45 ACP defensive loads typically run 185 to 230 grain. Pick a load your firearm cycles reliably and that you’ve tested at the range.
Most modern handguns can handle steel cased ammo, though some manufacturers recommend brass cases for cleaner cycling and easier extraction. Check your firearm’s owner manual before running steel cases.
