Bersa Thunder Pro Ultra Compact Parts

Parts types


We all know that the nature of man is to have fun with things. And having fun with handguns can have 2 extents. The first is the obvious, you take your pew to the range and shoot and shoot and repeat. The second part of having fun with a handgun is customisation of your Bersa Thunder Pro Ultra Compact with the help of gun parts. And thankfully the aftermarket handgun market is as versatile as can be. There are many companies that specialise in gun upgrades and maybe even more single gun enthusiasts that temper with their firearms to a safe extent.

The Bersa Thunder Pro Ultra Compact, as well as other handgun types, can be upgraded with accessories as well as have gun parts replaced. The market with gun parts is wide and there are many options for purchasing. Either in bulks, sets or separately. The options for your Bersa Thunder Pro Ultra Compactinclude sights, slide stops, barrels, triggers, cylinders, hammers, muzzles, trigger guards etc. All of those can be divided in broad categories: Action Parts, Barrel Parts, Books & Videos, Frame Parts, Grip Parts, Recoil Parts, Safety Parts, Sights, Slide Parts and Trigger Group Parts.


There are several parts and accessories such as handgun sights, grips or magazines which will be mentioned in this article briefly and you can find detailed information in articles about them here: sights, grips or magazines. And without further ado let’s get onto it.

Custom Handgun Sights

The simplest and one of the most useful part upgrades is a sight upgrade. Although this is not a specialised article about it, the basis stays the same - there are numerous options and the best place to find them is here. The pros of custom night sights are self explanatory, improved aim and faster target acquisition will never be useless and it’s always good to be faster than the bad guy.

Many handguns offer the option to have their sights exchanged either for night sights or red dot sights. Night sights can be divided into photoluminescent sights, tritium sights and fiber optic sights. Red dot sights, on the other hand differ from manufacturer to manufacturer but the basis is that they offer a stabilised point of aim.

Custom Handgun Grips

This is a great choice if you are looking for two things, more comfort and an outstanding look. Custom grips will improve your shooting because they will let your hand grip be more tight and secure and custom grips will improve your gun looks. Grip modifications will definitely improve your grip (no pun intended).

There are several types of grips that you can utilise. There are exchangable grips that come with the firearm from the manufacturer or you can invest in grip tapes, finger groove grips and many more. Check the options below.

Custom Match Grade Magazines

Magazines are a useful example of the saying there is always room for more ammo. Upgrade the capacity of your firearm by choosing a custom mag and feel a little bit safer. This modification won’t change your gun at all. Insufficient lubrication and faulty magazine springs and followers are often the case of mag failures. A match grade mag eliminates this and you will have a better feeling while defending yourself. Find more info below.

Mag upgrades differ and vary, you can just upgrade your baseplate or you can invest in a larger capacity magazine. You can also invest in getting a professional match grade mag that is just basically a factory magazine on steroids and is upgraded to perfection.

Custom Handgun Slides / Barrels

A pistol slide gets the job done and if you go one step forward and get your hands on a custom pistol slide you can not only have a slide that gets the job done but also looks the way you want. Many handguns have the option to have their slides customised, check them below.

Another possibility of upgrading your handgun is a new and custom barrel. Factory barrels can be always upgraded and a brand new barrel can minimise recoil and improve your shooting experience. The aftermarket with barrels is thriving so you can just delve in and look at all the options possible.

Extra Tip: Holsters

While not a part of the firearm itself, the handgun holster is one of the more important features of your carry. A properly retaining and safe holster will improve one of the most important parts of your carry - the speed of the draw and the safety of your firearm. Remember, always choose custom holsters. Find more info below.


You might ask if it’s good to modify a handgun that was sent to you from a producer. Or better, why to modify it when it’s 100% made by Bersa. Well the obvious reason is that no two shooters are the same and what is perfect for one might be not so perfect for the other. We strongly recommend visiting a trusty gunsmith even with the smallest modifications as that person has years of experience and a transparent portfolio of work done. But as always, it’s up to you. If you are skilled enough then just delve into modifications for your Bersa Thunder Pro Ultra Compact. The variety of the market is as wide as the variety of the gun market.

There are modifications available that not only upgrade how the gun works, which is the main aim of the market, there are numerous part modifications that also make your Bersa Thunder Pro Ultra Compact look better. And the saying that beauty is in the eye of the beholder may be true, but let's be honest, when you protect and defend the life of you or the ones around you, you might just do it with a gun that looks better than the average one. All thanks to gun parts.


You might ask if it’s good to modify a handgun that was sent to you from a producer. Or better, why to modify it when it’s 100% made by Bersa. Well the obvious reason is that no two shooters are the same and what is perfect for one might be not so perfect for the other. If you are able to do the change yourself go for it, but always remember that a small failure in your gunsmithing endeavour may result in tragedy. Most, if not all, handguns can be enhanced through services of gunsmiths. What can they do?

As we mentioned before, the several types of available custom parts let you upgrade your performance. There are also upgrades that improve the aesthetics of your firearm. The first type of upgrades - mechanical upgrades - have a little bit of warning packed with them. While you or your local gunsmith are making upgrades to any part of your firearm please consider that changing the trigger pull or pull weights will directly affect your performance.

Adrenalin doesn’t know the difference between two pounds or six pounds. And making your firearm lighter also changes the recoil so for the sake of disclaiming this, please consult a professional before doing any mechanical changes to your firearm. The latter category of upgrades - aesthetic ones - come without any warnings. Just please have one thing in mind - taste. Let’s not turn your prized firearm into a jokingly looking tool.
