Slide Lightening Cuts To Reduce Recoil

Lightening cut slides are not for combat or conceal carry and they’re pretty much range guns because they’re solely designed to reduce recoil besides looking slick.

A completely enclosed slide has a lot of recoil impulse that makes you feel what you normally feel when shooting a handgun where you have to kinda push the gun down.

A lighter slide with front cuts dramatically reduces the felt recoil when the slide rolls back when you fire a handgun.

Slide Serrations

Slide serrations helps you better gripping of the slide especially if you need more contact points or slippery fingers.

Front, top, sides and rear serrations gives the shooter multiple contact points to operate the slide if needed from various positions.

Some are more aggressive than others, so you need to visually look at the ones that fits you.

Knowing which one you like takes practice, I recommend finding serration texture patterns that you can easily grab firmly and also comfortably operate the slide without slipping.

Cycling Reliability

Most people are concerned with whether changing the weight of the slide would cause any malfunction.

The answer is yes, sometimes it happens when the parts of the gun were dramatically different than its original and it failed to function.

This means you have to problem solve and realize that recoil spring guide, trigger, caliber are all important parts that need to re-tuned as well.

Please see the recommended parts kit at the end of the article.

Optic Cut

Unity Tactical’s slide mounting optic adapter is the most unique design on the market, which allows one slide cut for multiple different optic adapters with the same mount.

Other slides generally cut the top ahead of the rear fixed sight. If you don’t want an optic makes sure you find one that offers you a cover plate.

Recommended Parts Kit To Balance The Performance

Whenever you change one part of the so much like the slide, you have to tune the rest of the gun to balance the performance attributes.

Trigger is one thing because you don’t want your trigger to be faster than the gun can cycle, which will cause misfire or out of battery.

Recoil spring needs to be tuned for different calibers and slide weights

Red dot sight weight can affect slide cycling, and that factor can influence more lightening cuts on the slide or a a heavier recoil round.

There are many options out there and you just have to test it, here I’m linking you to a source where they tested everything to show you what works so you can save time testing it yourself.
